If selling price is doubled, the profit triples. Find the profit percent.
Answer: Option
Explanation:
Let C.P. be Rs. x and S.P. be Rs. y.
Then, 3(y - x) = (2y - x) 
y = 2x.
Profit = Rs. (y - x) = Rs. (2x - x) = Rs. x.
 Profit % = |
 |
x | x 100 |  % = 100% |
| x |

Let's, c.p = x;
so, s.p = 2x;
profit = s.p - c.p.
So profit = 2x - x =x;
Profit % = (profit/ c.p )* 100 => (x / x) * 100.
So, profit % is 100.
so, s.p = 2x;
profit = s.p - c.p.
So profit = 2x - x =x;
Profit % = (profit/ c.p )* 100 => (x / x) * 100.
So, profit % is 100.

I am confused. How would I do it without using x and y?
Could somebody provide me with a logic? When I did it logically it came our to be 200%.

This question was asked in AFCAT 2/2015 and I answered 100% but when their answer sheet came out their answer was (199/3)%. I just don't get it.

@Redhotpoker.
yes, you are right S.P is 2x but.
Gain% = SP-CP/CP * 100 ( SP = 2x and CP = x).
= 2x-x/x * 100,
= 100%.

CP = x,
SP = 2x,
Profit = SP - CP.
= 2x-x.
Profit = x.
Profit(gain)% = (profit/CP)*100.
= (x/x)*100.
=100%.
SP = 2x,
Profit = SP - CP.
= 2x-x.
Profit = x.
Profit(gain)% = (profit/CP)*100.
= (x/x)*100.
=100%.

Let's suppose C.P=100 then If I double it S.P would become 200.
Profit would be 200-100=100, it's not tripled, the question is bit confusing.

Let C.P = 100.
Than S.P = 2X100 = 200.
and,
Profit = (SP-CP) = 200-100.
Profit = 100.
Now Profit% = 100X100/100 = 100% Ans, Option (B).
Than S.P = 2X100 = 200.
and,
Profit = (SP-CP) = 200-100.
Profit = 100.
Now Profit% = 100X100/100 = 100% Ans, Option (B).

2 S.P = 3 Profit.
2 S.P = 3 S.P - 3 C.P.
S.P = 3 C.P.
Assume C.P Rs. 1.
Profit = 2*100/1.
i.e 200.
Please tel me where I went wrong.
2 S.P = 3 S.P - 3 C.P.
S.P = 3 C.P.
Assume C.P Rs. 1.
Profit = 2*100/1.
i.e 200.
Please tel me where I went wrong.

I can't understand that it is saying if the selling price is doubled then the profit triples which means 2y=3 (y-x). Please suggest to me.

Another simple method:
Cost price = x,
Sell price = 2x,
Profit% = (sp-cp/cp) *100,
Profit% = (2x-x/x) *100,
Let x be 1.
(1/1) *100,
= 100.
Cost price = x,
Sell price = 2x,
Profit% = (sp-cp/cp) *100,
Profit% = (2x-x/x) *100,
Let x be 1.
(1/1) *100,
= 100.
